Feeding was done twice a day for up to 60 days. The results showed that growing Asian sea bass in fresh-water and seawater did not have a significant effect on growth performance indicators (except for the average final length) (P > 0.05). The mean secondary length in saltwater treatment was significantly higher (P < 0.05). Therefore, In addition, among the calculated nutritional parameters, only the food index received between treatments had a significant difference (P < 0.05) and other indicators and biochemical body compounds did not show a significant difference (P > 0.05). Cultivation of freshwater fish has a lower feed conversion ratio (0.92 ± 0.06); however, these changes were not significant. Overall, the study showed that it can withstand a wide range of different salinities for 60 days and grow well without showing any casualties. }, URL = {http://jair.gonbad.ac.ir/article-1-707-en.html}, eprint = {http://jair.gonbad.ac.ir/article-1-707-en.pdf}, journal = {Journal of Applied Ichthyological Research}, doi = {10.22034/jair.8.4.87}, year = {2021} }
